METALLIC VENTILATING Application filed April 3,

To all whom it may concern:

Be it known that I, GEORGE Drmnoo, a citizen of the United States of America, and resident of Steubenville, county of J elferson, and State of Ohio, have invented certain new and useful Improvements in Metallic Ventilating Shutters for Windows, of which the following is a specification.

This invention relates broadly to metallic windows, and more specificallyto a metallic blind or shutter for window openings.

The chief object of the invention is to provide an improved and practical metallic window structure designed primarily for use in mill and factory buildings, whereby the admission of light and the Ventilation of the building or room may be controlled.

A further object is to provide a sheetmetal ventilator of the character referred to in which all of the various parts of the frame possess forms affording great strength, rigidity and durability, and in which the louvers are adequately reinforced to enable them to effectively resist distortion.

With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, in which- Figure 1 is a rear elevation of a metallic window constructed in accordance with my invention;

Figure 2 is an end elevation of the same;

Figure 3 is a vertical section on line 3--3, Fig. 1; and

Figure 4 is a horizontal section on line H, Fig. 1.

Referring to said drawings, 1 and 2 indicate the horizontal top and bottom members, respectively, of a rectangular frame which is adapted to be rigidly mounted within a window opening (not shown) provided therefor in the wall of a building, as'of a factory or a mill, such opening being ordinarily located adjacent to the ceiling or the roof-eaves of such building to provide for admission of light as well as for ventilation through egress of heated air which collects at such high level. Said frame members 1 and 2 are of angle-iron form and are reversely disposed, the former facing inward and forming a hood or cow or the indow SHUTTER FOR WTNDOWS.

structure, while the latter faces outward with the inner upright thereof forming a bafiie whereby is prevented access to the interior of the building of water which drains from the overlying parts of the window structure or which is blown beneath the lowermost of the louvers is prevented.

The ends of said frame are constituted by upright inwardly-facing channel members 3 which at their opposite ends have the parallel inwardly-directed portions 9f thereof extended beyond the intermediate portion and turned laterally in opposite directions to form feet 4 that seat upon and are riveted to said top and bottom members 1 and 2.

Located midway between the end members 3, as shown in Fig. 1, is a member 5 similar to said members 3, the same dividing the shutter portion of the structure into two sections. In practice, the length of the individual sections as heretofore used approximates eight feet, but this may obviously be varied within suitable limits, the sections herein shown for illustrative purposes being of much less length. The number of sections and intermediate frame members 5 may manifestly be increased to any extent re uired.

ivotally mounted between each of the end members 3 and the intermediate member 5 of the frame is a plurality of louvers 5 which together constitute a closure for the opening that is bounded by said members and by the top and bottom members, said louvers being shaped to assume lapped relation when disposed in their upright closing positions.

Each of said louvers 6 is formed of a single piece of sheet metal and is shaped to form a central flat panel having its upper and lower lateral edges inclined in opposite directions from the plane thereof, the upper edge 6* being inclined outward from said plane at an angle of approximately fortyfive degrees, while the lower edge 6 is correspondingly inclined in an inward direction. Further, the relative arrangement of said louvers is such that, in the closed positions thereof, the upper inclined edge portion 6 of each, except the uppermost louver,

seats closely upon the inner face of the lower edge portion 6 of the neat-above louver.

thus providing a tight and practically weather-proof fit. The edge 6" of the lowermost louver lies outward of the upright portion of the lower frame member 2, while the edge 6 of the uppermost louver lies inward of, or behind, the vertical portion of the frame member 1.

Each louver has formed on each of the opposite ends of its flat panel portion an inwardly turned tongue or lug 7, and said lugs are centrally mounted upon the adjacent ends of pivot-pins or 'bolts 8 and 9 which are mounted horizontally in the parallel portions of the vertical end member 3 and the corresponding portions of the intermediate member 5.

To reinforce the louvers against chance distortion, each thereof has riveted upon the inner face of the flat panel portion thereof a centrally disposed stifi'ening bar 10 of angle-iron form, the same extending from end to end of said panel. Each louver also has riveted to the flat panel thereof substantially midway between its ends one leg of a cross-rib 11, also L-shaped in cross section, the same having its lower end overlapping said riveted leg of the bar 10 and having its upper end projectin somewhat above the bend intermediate sai panel and the inclined upper edge 6. Mounted upon pivot-pins or bolts 12 carried by the outstanding legs of the various vertically alined cross-ribs 11 is an upri ht bar 13 of angle-iron form which, in t e upright positions of the louvers, seats upon the edges of the outstanding legs of the longitudinal stiffening bars 10, said pivot-pins 12 being directed through the outstanding leg of said bar 13. vSaid bar 13 is designed to be shifted vertically for swinging the louvers to and from their closed position.

The means-herein shown for effecting the shifting of the bar 13 to open and close the louvers comprises a horizontal rod 14 journaled in the end of inwardl extending supporting arms 15 mounted in suitable positions upon the various upri ht frame members 3 and 5. Fixed to said rod, as by a pin 16 directed diametrically through the latter, is the lower member of a jointed arm comprising two pivotally connected members 17 and 18, the upper member 18 of which is pivotally attached to said bar 13. For effecting rotation of said rod 14, a pair of oppositely extending arms 19 and 20 are fixed on said rod, said arms having depending cords, chains or rods 21 and 22. Tractive force applied to said chain 21 will obviously effect rotation of said rod 14 for shifting the louvers from closed to open positions, while such force applied to the chain 22 will effect reverse, or closing, movement of said louvers.

It will be noted that the shutter structure described is constructed practically in its entirety of sheet metal and that the parts thereof are so shaped as to afford a maximum of strength and rigidity.

What is claimed is 1. A ventilating structure for windows, comprising upright frame members of inwardly-facing channel form, upper and lower horizontal frame members of angleiron form having the ends of said upright members attached thereto, said horizontal members being reversely disposed to con stitute shields, a plurality of louvers fitted within said frame and adapted to assume overlapping relation when in upright closed position, pivot-pins carriedby the upright frame members, said louvers having inturned lugs on their opposite ends mounted upon said pivot-pins, stiffening bars of angle-iron form mounted upon the inner faces of said louvers, and means for swinging said louvers to and from upright closing position.
